Probably using distance and time formula
distance= speed × time
Let x is the <span>unknown number
</span><span>quotient of an unknown number and 12 : x/12
</span><span>49 more than the quotient of an unknown number and 12 : x/12 + 49
so equation:
</span>x/12 + 49 = 53
Answer:
x=40° and y=50°
Step-by-step explanation:
45°+50°+2x+5=180°
100°+2x=180<-- subtract 100 to get x on one side
2x=80
x=40. Thus 2(40)+5 = 85.
85°+55°+x°=180
140°+x=180
x=40°
40°+90°(right angle)=130°, so 180 -130 would equal 50.
y=50°
The answer is B sorry i was wrong
3*(8+6)=3*14=42
is your answer
